Rename application to webdb

This commit renames the application container to webdb and drops the
test suffix in favour of using www.cacert.localhost directly. The server
certificate for www.cacert.localhost got an additional
subjectAlternativeName secure.cacert.localhost and is used for both
hostnames now.

Environment variables containing _APP have been renamed to _WEBDB to
keep consistency.
